IMPROVEMENT IN SEEDING-MACHINES.

Specification forming part of Letters Patent N0. 18,603, dated November 10, 18.57.

To all whom it may concern:

Be it known that I, EPHRAIM RUSSELL, of Contesville, in the county of Chester and State ot' Pennsylvania, have made certain new and useful Improvements in Seeding-Machines; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, ina-king part ot' this specifica-tion, in Which- Figure l is a top View; Fig. 2, a rear elevation; Fig. 3, a vertical section in the line l 2 of Fig. 2, and Fig. 4 a vertical section of the clutch and axle.

The letters of reference indicate the same parts in the different figures wherever they occur.

The following is a description of the construction of the machine.

The rectangular frame a is mounted by means ot' journals upon the divided axle b, to each portion of which a driving-Wheel, c, is fixed, revolving therewith. One part of the axle `b carries a cam-wheel, c', which revolves loosely between a shoulder, d, vand the hub of a hand-wheel, e, which, being screwed upon the axle b, operates as a friction-clutch when turned in the proper direction to press the cam-wheel against the shoulder, the end `of one part of the axle being pivoted in the end of the other. Above the cam-wheel, and pivoted to the two uprights f and g, is placed a rock-shaft, h, which carries the rocking lever and a tongue, k, to be acted upon by the movable cams l. The upper end of the rocking lever is pivoted to a connecting-rod, m, which has pivoted to its end a piece, n, extending from the sliding frame p by two uprights, 0.

The sliding frame p is formed of the two slides g'and a connecting-piece. Each ot' the side pieces of the frame is mortised to receive the vibrating seed-slides q, which ht into openings cnt into the conveyer-tubes r for that purpose, and into which they enter at every forward stroke of the slide and discharge the seed contained in the openings s.

The seed-hoppers t are each fastened to 'their respective frame-pieces, so as to cover the top of the seed-slides. The bottom piece of each hopper is mortised out, forming a chamber between the latter and the top of the slide for the receptiony of the seed from the Opening. The forward edge ot' each ofthe openings in the slides is chainfered ott', as shown in Fig. 3, to prevent the jamming of grains by the edge, and consequent breaking thereof and obstruction to the working ofthe machine. The cams l are made movable, and can be placed in different relative positions upon the cam-wheel, for the purpose of regulating the intervals of the operation of the slides. A spring, a, bears against the rear of the connecting-rod m for the purpose of forcing the slides back when relieved from the pressure of the cams Z. An angular piece ot' iron, c, is fastened to each slide, and enters the hopper just above its outlet to prevent clogging. A brush, x, strikes off the grainin the openings as the slides enter the conveyers.

The conveyer-spouts r consist of two parts hinged together, and are attached vertically to the frame, and heldin position by pins, which are easily shifted to regulate the depth to which the shoe 'L0 enters the furrow. The parts of the spout (which are hinged together at the rear) are prevented from separating by ordinary resistance by the springs z, which will keep the openings closed unless an obstacle is encountered, in which case they will yield and prevent breakage.

In operation, the hub ofthe hand-wheel being screwed up hard against the cam-wheel, the latter revolves as the machine is moved onward, thereby bringing the cams in snccession in contact with the tongue, which causes the slides to move forward and to enter the conveyer-spouts and deposit the seed contained in the openings. The tongue, being now released from the action of the cam, allows the spring to force the slides back to their former position, whereby the openings are again filled, to be emptied by the next forward motion of the slide. The number ot' vibrations of the seed-slides during one revolution ofthe drivin g-wheels may be adj usted and regulated by the removal or addition of cams on the periphery of the cani-wheel. They are for this purpose inserted into inortices formed therein, and secured by meansot pins. The size of the openings to contain the seed may be adjusted by means of sliding bottoms, and the discharge of seed thereby regulated.

Having thus fully described my improvements, what I claim as my invention, and dell In testimonywhereoflhave signed myname sire to secure by Letters Patent, is to this specification before two subscribingwit- 1. The combination of the screw frictionnesses.
